1. HISTORICAL INTRODUCTIONLT HoUG H this Report covers principally the most modern developments in the field of television, a brief historical outline of the inventions, discoveries and improvements which contributed most to its progress still serves a useful purpose. During the past several decades the technical advances in all branches of electrical communication-particularly radio-have been nothing short of phenomenal. It is therefore not altogether surprising that the development of electronic television is likely to be taken as a matter of course, and the fact that it had its humble beginnings often completely forgotten.Probably the first practical.discovery leading to the development of modem television was that which occurred in Valentia, Ireland, in 1873 (Larner, 1929), Recent television developmentsI39 1 'I II I ~, , , plar 140.
